DUBAI, United Arab Emirates (AP) -- Fifth-seeded Agnieszka Radwanska advanced to the second round of the Dubai Tennis Championships Tuesday after defeating Aleksandra Wozniak of Canada 6-1, 6-7 (8), 7-5.
The 22-year-old Radwanska cruised through the first set in 27 minutes, but she needed another two hours to win her opening match in Dubai. After losing the second set on a tiebreaker, Radwanska struggled to regain concentration in the third, but rallied from 5-3 down to win 7-5.
Later Tuesday, seventh-seeded Francesca Schiavone will play Ana Ivanovic, and sixth-seeded Marion Bartoli of France will meet Shuai Peng of China.
Two more players joined the list of withdrawals. Dominika Cibulkova of Slovakia retired Tuesday with a hamstring injury while trailing Iveta Benesova 3-1, and Maria Kirilenko withdrew with a neck injury.
Australian Open champion Victoria Azarenka is the top-seeded player in Dubai. The top-ranked Belarusian will meet Julia Goerges of Germany in her opening match on Wednesday.
The field also includes defending champion Caroline Wozniacki and U.S. Open winner Sam Stosur. However, Wimbledon champion Petra Kvitova, French Open winner Li Na and Vera Zvonareva withdrew because of illness or injury on Monday.
